To fine tune the refresh rate for your display

Refresh rate refers to the frequency at which the entire screen is refreshed. Specifically, refresh rate indicates how many times per second the electron beam in the picture tube is moved from top to bottom in the case of a CRT (analog display). Note: This frequency is limited by the display's maximum horizontal scan rate and the current resolution, as higher resolution implies more scan lines.

Note: You must be an advanced user and have knowledge of display timing concepts in order to work with custom timings for your HDTV display.

  1. From the NVIDIA Control Panel navigation tree pane, under Display, click Change resolution.

  2. Click the image that represents the display you want to affect.

  3. Make your adjustments by either editing an existing custom resolution, or creating a new custom resolution.
